gulp-inline-css Build Status

Inline your CSS properties into the style attribute in an html file. Useful for emails.

Inspired by the grunt plugin grunt-inline-css. Uses the juice library.

How It Works

This gulp plugin takes an html file and inlines the CSS properties into the style attribute.

/path/to/file.html:

<html>
<head>
  <style>
    p { color: red; }
  </style> 
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <p>Test</p>
</body>
</html>

style.css

p {
  text-decoration: underline;
}

Output:

<html>
<head>
</head>
<body>
  <p style="color: red; text-decoration: underline;">Test</p>
</body>
</html>

What is this useful for ?

  • HTML emails. For a comprehensive list of supported selectors see here
  • Embedding HTML in 3rd-party websites.
  • Performance. Downloading external stylesheets delays the rendering of the page in the browser. Inlining CSS speeds up this process because the browser doesn't have to wait to download an external stylesheet to start rendering the page.

Install

Install with npm

npm install --save-dev gulp-inline-css

Usage

var gulp = require('gulp'),
    inlineCss = require('gulp-inline-css');
 
gulp.task('default', function() {
    return gulp.src('./*.html')
        .pipe(inlineCss())
        .pipe(gulp.dest('build/'));;
});

With options:

var gulp = require('gulp'),
    inlineCss = require('gulp-inline-css');
 
gulp.task('default', function() {
    return gulp.src('./*.html')
        .pipe(inlineCss({
             applyStyleTags: true,
             applyLinkTags: true,
             removeStyleTags: true,
             removeLinkTags: true
        }))
        .pipe(gulp.dest('build/'));;
});

Options are passed directly to juice.
